D-Wave Systems announced Tuesday (Sept. 28, 2016) a new 2000-qubit processor, doubling the number of qubits over the previous-generation D-Wave 2X system. The new system will enable larger problems to be solved and performance improvements of up to 1000 times.

D-Wave’s quantum system runs a quantum-annealing algorithm to find the lowest points in a virtual energy landscape representing a computational problem to be solved. The lowest points in the landscape correspond to optimal or near-optimal solutions to the problem. The increase in qubit count enables larger and more difficult problems to be solved, and the ability to tune the rate of annealing of individual qubits will enhance application performance.

Anyone upgrading their D-Wave 2?

We’re actually a little bit scared of it.

Hmmm; like the graphic reminds of one of my posts.

In Brief.

Scientists have developed a device that can guarantee producing an endless sequence of entangled photons.

Nice article; however, not sure if the author is aware Los Alamos already has a quantum net as well as some Europe banks have the capabilities and 4 months ago it was announced that a joint effort by various countries from Europe, Asia, etc. have come together to re-engineer the Net infrastructure with QC technology…

Maybe the quantum will giveth what the quantum taketh away… at least when it comes to secure transmissions.

There’s been much speculation that emerging quantum computers will become capable of breaking advanced public key cryptography systems, such as 2048-bit RSA. This might leave encrypted data transmissions exposed to anyone who happens to own such a quantum computer.

Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow’s computer technology. For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum computers.

“Experiments investigating the applicability of optical quantum technology so far have often claimed whole laboratory spaces,” explains Professor Ralph Krupke of the KIT. “However, if this technology is to be employed meaningfully, it must be accommodated on a minimum of space.” Participants in the study were scientists from Germany, Poland, and Russia under the leadership of Professors Wolfram Pernice of the Westphalian Wilhelm University of Münster (WWU) and Ralph Krupke, Manfred Kappes, and Carsten Rockstuhl of the Karlsruhe Institute of Technology (KIT).

The light source for the quantum photonic circuit used by the scientists for the first time were special nanotubes made of carbon. They have a diameter 100,000 times smaller than a human hair, and they emit single light particles when excited by laser light. Light particles (photons) are also referred to as light quanta. Hence the term “quantum photonics.”

This doesn’t surprise me at all given how we can leverage synthetic diamonds and their crystal formations for light networks, QC, and now storage.

Nuclear spins in diamond can store photonic information with high fidelity and have coherence times that exceed 10s, making diamond potentially useful as a node in quantum communications.

The University of Rochester has begun work on what they call a Quantum Enigma Machine. This new machine is said to be responsible for unbreakable encryption. It will also shorten encryption keys, and make data interception much more difficult than it already is.

American Mathematician Claude Shannon came up with a binary system that would allow him to transmit messages under three stipulations: the key is random, only used once, and it has to be as long as the message itself is.

Recent studies show that scientists are theorizing that they could send a message with unbreakable encryption with a key that is much shorter than the message itself. Their theory may soon become fact as researchers have developed the quantum enigma machine.

Researchers at the Karlsruhe Institute of Technology say they have developed a quantum photonic circuit with an electrically driven light source. Described as a ‘complete quantum optical structure on a chip’, the development is said to fulfil one condition for the use of photonic circuits in optical quantum computers.

“Experiments investigating the applicability of optical quantum technology have often claimed whole laboratory spaces,” said Professor Ralph Krupke. “However, if this technology is to be employed meaningfully, it must be accommodated on a minimum of space.”

The light source for the quantum photonic circuit is carbon nanotubes which emit single particles of light when excited by a laser. Because they emit single photons, carbon nanotubes are attractive as light sources for optical quantum computers.
